Sega today released an update to its classic gaming title Sonic the Hedgehog. The update brings Apple TV support to the table, adding more value to the universal app.

Those of you who’ve already purchased Sonic the Hedgehog on iOS will therefore be able to enjoy the game on the 4th generation Apple TV free of charge.

For the moment, the new Apple TV’s accessory compatibility can fairly be described as “confusing.” It’s confirmed that Bluetooth speakers and headphones — previously unsupported by older Apple TVs — work with the new model. On the other hand, Bluetooth keyboards, which previously worked with Apple TVs, do not. And Bluetooth game controllers… well, if they were Made For iPhone (or iPad), they work with the new Apple TV. But contrary to some erroneous early reports, if they were made for other devices (say, the PlayStation 4), they don’t.

So even though SteelSeries’ Nimbus ($50) has been pitched as the first “gamepad controller for Apple TV,” it’s kinda not. The company’s earlier Stratus (now only $40 refurbished) works with the Apple TV, as do Mad Catz’ nicer C.T.R.L.i and Micro C.T.R.L.i controllers. However, Nimbus is launching with newer technology at a not-insane price point. It has a Lightning connector built in for recharging an integrated 40-hour battery, a Bluetooth 4.1 wireless chip, and a design that was apparently — despite obvious similarities to many other controllers — co-developed by Apple itself. It also is the first accessory to ship with Apple’s new “Made for Apple TV” logo on the box. Here are some early thoughts on the Nimbus based on my hands-on experiences…
